---Tempered glass

• Safety: when broken, tempered glass becomes small granules, which prevent substantial hurt to human body.
  
• High strength: the strength of tempered glass is 4 to 5 times that of annealed glass.
  
• Thermal stability: tempered glass has excellent thermal stability, which can withstand up to 300 degree Celsius thermal shock.
  
• Tempered glass is a kind of safety glass and is widely used in places which call for high mechanical strength and safety, such as glazed door, curtain wall, vertical window, partition wall, and partition screen close to heat source and subject to violent thermal shock.
  

 ---Heat Strengthened glass

• Heat-strengthened glass differs from tempered glass in its surface compression; its mechanical strength is about 1.6-2 times that of annealed glass. Heat-strengthened glass has outstanding thermal stability, and its flatness is close to that of annealed glass and better than that of tempered glass.

• Conforming to ASTM1048, the American standard
  
• Conforming to BS6206, the British standard
  
• Conforming to GB15763.2, the Chinese standard
  
• Conforming to GB17841, the Chinese standard
  

Production Capacity:

Tempered and heat-strengthened glass is obtained by heating ordinary glass to its softening point and then suddenly cooling down to form compression in the surface layer of the glass, thus the mechanical strength is increased by times.

CSG owns twenty seven glass tempering lines by Tamglass of Finland with an annual production capacity of 22 million square meters and four curving and tempering lines by North glass of China with an annual capacity of 1.3 million square meters.
